WARNING
1 You can not specify the table that includes different
kind of address type or discontinuous address area.
In this case, operation is not guaranteed.
2 You have to set the "Storage address of number of
data table elements" and the "Data table head
address" not to exceed the limit of its continuous
address area. If the table exceeds the limit of the
continuous address area, operation is not
guaranteed. For example, when a range of address
R is 0 to 7999 and the "Format specification" is set
to 1 and the "Data table head address" is set to
"R7990", you can set 10 or less to the "Storage
address of number of data table elements".
Error output (W1)
W1 = 0: No error
W1 = 1: Error found. In the case where the index value set in "(e)
Index storage address" exceeds the value set in "(b) Storage
address of number of data table elements", it becomes W1 =
1. The reading or writing of the data table isn't executed.
When "(a) Format specification" is used for operation in the
extended format, if the values of one or more elements in the
index array specified in (e) are greater than the value set in
"(b) Storage address of number of data table elements", it
becomes W1 = 1. The reading or writing of a data table is
executed for the normal index values but not executed as for
the wrong index values.
